 dow^nward; a deep median sulcus in front of mesogastric region. Sur- 

 face rough with squamiform tubercles, larger anteriorly than poster- 

 iorly; stiff black setae proceed chiefly from the tubercles. Frontal 

 margin between orbits armed with numerous short, obtuse spines. 

 Antero-lateral margins with 7 to 9 spiniform teeth, often themselves 

 denticulate. Orbits further from antennae than in the genus Eriphia. 

 Below outer angle of orbit a deep emargination, deeper than wide. 



Chelipeds tuberculate or granulate above and outside, and hands 

 inside. Fingers of major chela rounded, blunt; those of minor chela 

 broader, hollowed out in a long spoon, edge mostly thin. Legs very 

 broad, compressed, non-granulate; upper border of meri thin and 

 crenulated.
